If any instruction would jump to a predefined address, symbolic name of the jump target will be additionally displayed. If the destination location is within the currently displayed symbol an \texttt{->}~arrow will be prepended to the name. Hovering the \faMousePointer{}~mouse pointer over such symbol name will highlight the target location. Clicking on it with the \LMB{}~left mouse button will focus the view on the destination instruction, or switch view to the destination symbol.
Enabling the \emph{\faShare{}~Jumps} option will show jumps within the symbol code as a series of arrows from the jump source to the jump target. Hovering the \faMousePointer{}~mouse pointer over the jump arrow will display jump information tooltip and will also draw the jump range on the scroll bar, as a green line. Jump target location will be marked by a horizontal green line. Jumps going out of the symbol\footnote{This includes jumps, procedure calls and returns. For example, in x86 assembly the respective operand names can be: \texttt{jmp}, \texttt{call}, \texttt{ret}.} will be indicated by a smaller arrow pointing away from the code.

The \emph{AT\&T} switch can be used to select between \emph{Intel} and \emph{AT\&T} assembly syntax. Beware that microarchitecture data is only available if Intel syntax is selected.

Enabling the \emph{\faTruckLoading{}~Latency} option will display graphical representation of instruction latencies on the listing. Minimum latency of an instruction is represented with a red bar, while the maximum latency is represented by a yellow bar.
Clicking on the \emph{\faFileImport{}~Save} button lets you write the disassembly listing to a file. You can then manually extract some critical loop kernel and pass it to a CPU simulator, such as \emph{LLVM Machine Code Analyzer} (\texttt{llvm-mca})\footnote{\url{https://llvm.org/docs/CommandGuide/llvm-mca.html}}, in order to see how the code is executed and if there are any pipeline bubbles. Consult the \texttt{llvm-mca} documentation for more details.
